Little is known about the classroom practice of British teachers teaching i
nvestigative science, other than the problematic implementation of assessme
nt demands since around 1990. In this paper some preliminary theory is form
ed from the shared reflections of some Scottish leachers at a symposium on
the teaching of investigative science. Three different ways of integrating
investigations into their teaching were apparent: they could be added on as
a separate whole class exercise,added in through rewriting activities inve
stigatively and supported as they arose ad hoc from pupils. Other emergent
insights into leacher thinking are developed and discussed and some connect
ions made with relevant literature. Teacher involvement, teacher and beginn
er knowledge, pupil knowledge base, level of investigation and resource man
agement are examples of implicit concepts which begin to constitute a basis
for fuller understanding and exploration of the teaching context of invest
igations in science.
